SMT xaiv thiab tso tshuabhais txog cov ntawv luv ntawm cov txheej txheem thev naus laus zis raws li PCB.PCB txhais tau tias yog ib tug Printed Circuit Board.
Surface Mounted Technology yog qhov nrov tshaj plaws Technology thiab txheej txheem hauv kev lag luam hluav taws xob sib dhos tam sim no.Printed Circuit Board yog ib qho cuab yeej siv hluav taws xob hauv Circuit Court uas cov khoom sib dhos saum npoo tsis muaj pins lossis cov hlau lead luv yog ntsia rau saum npoo ntawm cov ntawv luam tawm Circuit boards lossis lwm yam substrates thiab soldered ua ke los ntawm kev rov ua vuam, dip vuam, thiab lwm yam.
Feem ntau, cov khoom siv hluav taws xob uas peb siv yog ua los ntawm PCB ntxiv rau ntau yam capacitors, resistors thiab lwm yam khoom siv hluav taws xob raws li kev tsim qauv ntawm daim duab kos duab, yog li txhua yam ntawm cov khoom siv hluav taws xob xav tau ntau yam sib txawv ntawm SMT ua cov txheej txheem.
SMT txheej txheem txheej txheem: solder paste printing -> SMT mounting ->reflow qhov cub->AOIkhoom sivoptical soj ntsuam -> tu -> board.
Vim yog cov txheej txheem thev naus laus zis ntawm kev ua haujlwm nyuaj SMT, yog li muaj ntau lub chaw ua haujlwm SMT, rau SMT zoo tau raug txhim kho, thiab cov txheej txheem SMT, txhua qhov txuas yog qhov tseem ceeb, tsis tuaj yeem muaj qhov yuam kev, hnub no me me ua nrog txhua tus ua ke kawm SMT reflow welding tshuab tau qhia thiab cov cuab yeej tseem ceeb hauv kev ua haujlwm.
Reflow soldering cov cuab yeej yog cov cuab yeej tseem ceeb hauv SMT txheej txheem sib dhos.Qhov zoo ntawm PCBA solder sib koom yog nyob ntawm qhov ua tau zoo ntawm cov khoom siv reflow soldering thiab qhov chaw ntawm qhov kub thiab txias.
Lub tshuab reflow vuam tau ntsib kev txhim kho ntawm cov phaj hluav taws xob cua sov, quartz infrared raj cua sov, infrared cua kub cua sov, yuam cua kub cua sov, yuam cua kub cua sov thiab nitrogen tiv thaiv thiab lwm yam ntaub ntawv.
Cov kev xav tau ntau ntxiv rau cov txheej txheem txias ntawm reflow soldering kuj tau txhawb txoj kev loj hlob ntawm cov chaw txias rau cov khoom siv reflow soldering, xws li cov cua txias thiab cua txias ntawm chav tsev kub rau cov dej txias uas tsim los rau cov hlau lead-free soldering.
Reflow soldering khoom vim cov txheej txheem ntau lawm ntawm kev tswj qhov kub thiab txias, qhov kub tsis sib xws hauv qhov kub thiab txias, hloov ceev thiab lwm yam yuav tsum tau ua.Thiab tsim los ntawm peb cheeb tsam kub tsib cheeb tsam, rau qhov kub thiab txias cheeb tsam, xya cheeb tsam kub, yim kub cheeb tsam, kaum kub cheeb tsam thiab lwm yam sib txawv vuam tshuab.
Qhov tseem ceeb ntawm cov khoom siv reflow soldering
1. Tus naj npawb, qhov ntev thiab qhov dav ntawm qhov kub thiab txias;
2. Symmetry ntawm cov cua sov sab saud thiab qis;
3. Kev sib txawv ntawm qhov kub thiab txias ntawm thaj chaw kub;
4. Kev ywj pheej ntawm qhov kub thiab txias ntawm kev sib kis ceev tswj;
5, inert gas tiv thaiv vuam muaj nuj nqi;
6. Gradient tswj ntawm qhov chaw txias txias qhov kub poob;
7. Qhov kub siab tshaj plaws ntawm reflow vuam rhaub;
8. Kub tswj precision ntawm reflow soldering rhaub;
